If it's really cold and it's right after you start your Jeep, it could be the power steering pump working really hard to move that thick steering fluid. Would put more load on the engine and perhaps slow down the alternator a bit. You can usually see this happen if you turned it to full lock and kept trying to turn more, too, to verify. That's the only thing I can think of. It's not a problem and is pretty normal for vehicles I've owned.
